Assuming a 10 % drop-out rate, it was planned to enroll 540 subjects to yield the minimum required total of 486 patients. 2.3.2 Statistical Analysis The primary objective was to determine how the rate of TEAEs (ocular and nonocular) reported with besifloxacin ophthalmic suspension 0.6 % used three times daily
for 7 days compared with the rate reported with vehicle alone. Exact 95 % confidence intervals were constructed around the proportion of subjects and eyes with each TEAE, and Fisher’s exact test was used to test for differences between treatment groups. A similar approach was used to summarize treatment-related Selleckchem MCC950 AEs. 3 Results 3.1 Study Populations The safety population included 514 subjects: 344 subjects HDAC cancer treated with besifloxacin ophthalmic suspension 0.6 % and 170 subjects treated with vehicle. The mITT population included 299 subjects,
212 treated with besifloxacin ophthalmic suspension 0.6 % and 87 treated with vehicle. In both populations, baseline demographics were similar between treatment groups (Table 1), as was ocular medical history. In the safety population, pediatric subjects (≤17 years of age) comprised 43.0 and 35.3 % of the besifloxacin and vehicle groups, respectively.
